What is INSTANCE SELECTION? What does INSTANCE SELECTION mean? INSTANCE SELECTION meaning - INSTANCE SELECTION definition - INSTANCE SELECTION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Instance selection (or dataset reduction, or dataset condensation) is an important Data pre-processing step that can be applied in many Machine learning (or Data mining) tasks. Approaches for instance selection can be applied for reducing the original dataset to a manageable volume, leading to a reduction of the computational resources that are necessary for performing the learning process. Algorithms of instance selection can also be applied for removing noisy instances, before applying learning algorithms. This step can improve the accuracy in classification problems. Algorithm for instance selection should identify a subset of the total available data to achieve the original purpose of the data mining (or machine learning) application as if the whole data had been used. Considering this, the optimal outcome of IS would be the minimum data subset that can accomplish the same task with no performance loss, in comparison with the performance achieved when the task is performed using the whole available data. Therefore, every instance selection strategy should deal with a trade-off between the reduction rate of the dataset and the classification quality. The literature provides several differente algorithms for instance selection. They can be distinguished from each other according to several different criteria. Considering this, instance selection algorithms can be grouped in two main classes, according to what instances they select: algorithms that preserve the instances at the boundaries of classes and algorithms that preserve the internal instances of the classes. Within the category of algorithms that select instances at the boundaries it is possible to cite DROP3, ICF and LSBo. On the other hand, within the category of algorithms that select internal instances it is possible to mention ENN and LSSm. In general, algorithm such as ENN and LSSm are used for removing harmful (noisy) instances from the dataset. They do not reduce the data as the algorithms that select border instances, but they remove instances at the boundaries that have negative impact in the data ming task. They can be used bay other instance selection algorithms, as a filtering step. For example, the ENN algorithm is used by DROP3 as the first step, and the LSSm algorithm is used by LSBo. There is also another group os algorithms that adopt different selection criteria. For example, the algorithms LDIS and CDIS select the densest instances in a given arbitrary neighborhood. The selected instances can include both, border and internal instances. The LDIS and CDIS algorithms are very simple and select subsets that are very representative of the original dataset. Besides that, since they search by the representative instances in each class separately, they are faster (in terms of time complexity and effective running time) than other algorithms, such as DROP3 and ICF.

Regular Expressions (Regex) Tutorial: How to Match Any Pattern of Text
 
37:55
In this regular expressions (regex) tutorial, we're going to be learning how to match patterns of text. Regular expressions are extremely useful for matching common patterns of text such as email addresses, phone numbers, URLs, etc. Almost every programming language has a regular expression library, so learning regular expressions with not only help you with finding patterns in your text editors, but also you'll be able to use these programming libraries to search for patterns programmatically as well.

Latanya Sweeney: When anonymized data is anything but anonymous
 
36:22
Relatively simple data science experiments can yield major insights and have a significant impact. Many experiments in data science are expensive and time consuming to pursue. But Latanya Sweeney, professor of government and technology at Harvard University, has shown that even relatively simple studies conducted by students can have a significant impact on public policy and society. As a student in the 1990s, Sweeney discovered that by applying a couple of filters to a database containing supposedly anonymized health records of Massachusetts state employees, she was able to identify the medical history of Gov. William Weld. That simple experiment led to a broader conclusion: Most people in the United States are the only ones in their ZIP code with a particular date of birth, which means it is relatively easy to discover their identities in much the same way Sweeney found Weld’s history. “That impact -- the ability to have a simple experiment and have dramatic impact – was huge, and something that stayed with me forever. That simple experiment was quoted in the preamble of HIPAA and the rewrite of privacy laws around the world,” Sweeney said during a talk at this year’s Women in Data Science (WiDS) conference at Stanford University. Over the years, Sweeney and her associates have flagged numerous instances of flaws in public databases that have caused significant harm. And they’ve found instances where data sources have been misused or applied in a discriminatory manner. A query by a reporter prompted Sweeney to look for a correlation between names typically given to African-Americans and online ads mentioning arrest records. She found it. Online searches containing a name that sounds like it belongs to a black person were 80 percent more likely to generate an ad mentioning arrest records than searches for stereotypically white names. “Somebody goes online to see what they can find out about you and Googles your name. And if the ads are popping up implying that you have an arrest record, then in fact, you’re at a disadvantage. It’s not about the intent or whether it was intended,” said Sweeney, who was chief technology officer for the Federal Trade Commission from January 2014 until December 2014. A study by Sweeney’s students found that a major SAT tutoring company charged higher prices to Asians. And Airbnb modified its pricing policies after the students found price discrimination against certain groups. Referring to the examples she gave during her talk, Sweeney said: “I like to think I’m really smart, but the truth is these are really simple experiments. But they have profound impact because they empower someone else to be able to do their job better.”
K-means clustering: how it works
 
07:35
Full lecture: http://bit.ly/K-means The K-means algorithm starts by placing K points (centroids) at random locations in space. We then perform the following steps iteratively: (1) for each instance, we assign it to a cluster with the nearest centroid, and (2) we move each centroid to the mean of the instances assigned to it. The algorithm continues until no instances change cluster membership.

KD tree algorithm: how it works
 
03:09
[http://bit.ly/k-NN] K-D trees allow us to quickly find approximate nearest neighbours in a (relatively) low-dimensional real-valued space. The algorithm works by recursively partitioning the set of training instances based on a median value of a chosen attribute. When we get a new data instance, we find the matching leaf of the K-D tree, and compare the instance to all the training point in that leaf.

Object Region Mining With Adversarial Erasing: A Simple Classification to ...
 
09:22
Yunchao Wei, Jiashi Feng, Xiaodan Liang, Ming-Ming Cheng, Yao Zhao, Shuicheng Yan We investigate a principle way to progressively mine discriminative object regions using classification networks to address the weakly-supervised semantic segmentation problems. Classification networks are only responsive to small and sparse discriminative regions from the object of interest, which deviates from the requirement of the segmentation task that needs to localize dense, interior and integral regions for pixel-wise inference. To mitigate this gap, we propose a new adversarial erasing approach for localizing and expanding object regions progressively. Starting with a single small object region, our proposed approach drives the classification network to sequentially discover new and complement object regions by erasing the current mined regions in an adversarial manner. These localized regions eventually constitute a dense and complete object region for learning semantic segmentation. To further enhance the quality of the discovered regions by adversarial erasing, an online prohibitive segmentation learning approach is developed to collaborate with adversarial erasing by providing auxiliary segmentation supervision modulated by the more reliable classification scores. Despite its apparent simplicity, the proposed approach achieves 55.0% and 55.7% mean Intersection-over-Union (mIoU) scores on PASCAL VOC 2012 val and test sets, which are the new state-of-the-arts.

Apriori Algorithm (Associated Learning) - Fun and Easy Machine Learning https://www.udemy.com/machine-learning-fun-and-easy-using-python-and-keras/?couponCode=YOUTUBE_ML Limited Time - Discount Coupon Apriori Algorithm The Apriori algorithm is a classical algorithm in data mining that we can use for these sorts of applications (i.e. recommender engines). So It is used for mining frequent item sets and relevant association rules. It is devised to operate on a database containing a lot of transactions, for instance, items brought by customers in a store. It is very important for effective Market Basket Analysis and it helps the customers in purchasing their items with more ease which increases the sales of the markets. It has also been used in the field of healthcare for the detection of adverse drug reactions. A key concept in Apriori algorithm is that it assumes that: 1. All subsets of a frequent item sets must be frequent 2. Similarly, for any infrequent item set, all its supersets must be infrequent too.

UML Class Diagram Tutorial
 
10:17
Learn how to make classes, attributes, and methods in this UML Class Diagram tutorial. There's also in-depth training and examples on inheritance, aggregation, and composition relationships. UML (or Unified Modeling Language) is a software engineering language that was developed to create a standard way of visualizing the design of a system. And UML Class Diagrams describe the structure of a system by showing the system’s classes and how they relate to one another. This tutorial explains several characteristics of class diagrams. Within a class, there are attributes, methods, visibility, and data types. All of these components help identify a class and explain what it does. There are also several different types of relationships that exist within UML Class Diagrams. Inheritance is when a child class (or subclass) takes on all the attributes and methods of the parent class (or superclass). Association is a very basic relationship where there's no dependency. Aggregation is a relationship where the part can exist outside the whole. And finally, Composition is when a part cannot exist outside the whole. A class would be destroyed if the class it's related to is destroyed.

2012-04-11 - : K-Anonymity in Social Networks: A Clustering Approach - CERIAS Security Seminar
 
53:15
Recorded: 04/11/2012 CERIAS Security Seminar at Purdue University : K-Anonymity in Social Networks: A Clustering Approach Traian Truta, Northern Kentucky University The proliferation of social networks, where individuals share private information, has caused, in the last few years, a growth in the volume of sensitive data being stored in these networks. As users subscribe to more services and connect more with their friends, families, and colleagues, the desire to use this information from the networks has increased. Online social interaction has become very popular around the globe and most sociologists agree that this will not fade away. Social network sites gather confidential information from their users (for instance, the social network site PacientsLikeMe collects confidential health information) and, as a result, social network data has begun to be analyzed from a different, specific privacy perspective. Since the individual entities in social networks, besides the attribute values that characterize them, also have relationships with other entities, the risk of disclosure increases. In this talk we present a greedy algorithm for anonymizing a social network and a measure that quantifies the information loss in the anonymization process due to edge generalization. Traian Marius Truta is an associate professor of Computer Science at Northern Kentucky University. He received his Ph.D. in computer science from Wayne State University in 2004. His major areas of expertise are data privacy and anonymity, privacy in statistical databases, and data management. He has served on the program committee of various conferences such as International Conference on Database and Expert Systems Applications (DEXA), Pacific-Asia Conference on Knowledge Discovery and Data Mining (PAKDD), ACM Symposium of Applied Computing (SAC), and International Symposium on Data, Privacy, and E-Commerce (ISDPE). He received the Yahoo Research! Best Paper Award for Privacy, Security, and Trust in KDD 2008 (PinKDD) for the paper �A Clustering Approach for Data and Structural Anonymity in Social Networks� in 2008.

k nearest neighbor (kNN): how it works
 
09:05
[http://bit.ly/k-NN] The k-nearest neighbor (k-NN) algorithm is based on the intuition that similar instances should have similar class labels (in classification) or similar target values (regression). The algorithm is very simple, but is capable of learning highly-complex non-linear decision boundaries and regression functions. On the downside, the algorithm is computationally expensive, and is prone to overfitting.

Getting Started with Weka - Machine Learning Recipes #10
 
09:24
Hey everyone! In this video, I’ll walk you through using Weka - The very first machine learning library I’ve ever tried. What’s great is that Weka comes with a GUI that makes it easy to visualize your datasets, and train and evaluate different classifiers. I’ll give you a quick walkthrough of the tool, from installation all the way to running experiments, and show you some of what it can do. This is a helpful library to have while you’re learning ML, and I still find it useful today to experiment with new datasets. Note: In the video, I quickly went through testing. This is an important topic in ML, and how you design and evaluate your experiments is even more important than the classifier you use. Although I publish these videos at turtle speed, I’ve started working on an experimental design one, and that’ll be next! Also, we will soon publish some testing tips and best practices on tensorflow.org (https://goo.gl/nZcS5R).

k-NN 2: classification and regression
 
08:40
[http://bit.ly/k-NN] The k-NN algorithm operates as follows. For a new test instance, we first compute its distance to all the N training instances, and keep a small number k of nearest neighbours. For classification, we then predict the most dominant class among the k neighbours. For regression, we compute the mean target value across the k neighbours.
